Answer:
1 All the spheres interact with other spheres. For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere). ... Flooding rivers wash away soil. 2 As the global human population continues to grow, so too does our impact on the environment. The ingenuity with which our species has harnessed natural resources to fulfill our needs is dazzling.
3 Humans impact the environment through their interactions in many different ways, such as overpopulation, pollution, and the burning of fossil fuels. Human environment interactions have resulted in impacts, such as climate change, soil erosion, and air pollution. 4 All the spheres interact with other spheres. For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere). 5 The National Environmental Policy Act of 1969 committed the United States to sustainability, declaring it a national policy “to create and maintain conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirements of present and future generations.”
Answer:
Closed system.
Explanation:
Robot is an closed system because there is no transfer of mass but transfer of energy occurs from robot to its surrounding. According to the definition of closed system, closed system is a type of system in which there is only transfer of energy occurs while in open system both mass and energy can be transferred from the system to their surrounding. So no mass transferred from the robot only energy in the form of mechanical energy is transferred.
An arrangement of genes consisting of an operator, a promoter, and a repressor is an OPERON.
Answer:
The point that does NOT accurately indicate a carbon transfer in the carbon cycle is that burning of wood and debris pulls carbon from the atmosphere to use as energy.
Explanation:
The carbon cycle involves the journey that carbon makes between living organisms and their surrounding environment, i.e. the entire biosphere, geosphere, hydrosphere and atmosphere, and is therefore considered a biogeochemical cycle.
In living organisms, inorganic carbon is taken up by plants to make organic molecules, which will be used by animals - which release CO₂ into the atmosphere - or dead organic matter provides carbon to the soil.
The combustion of wood and debris involves the oxidation of a combustible material -which requires oxygen from atmosphere- to then release CO₂ as a product. So it is incorrect to say that burning of wood and debris pulls carbon from the atmosphere to use as energy.
